Specification of Letters Patent.

Patented Feb. e, 1908.

Application filed August 10. 1905 Serial No.- 275.542.

To all whom it may concern:

Be it known that l, llimviuzn lil. GoLn, a citizen of the United States, residing in the borough of Munhnttnn, city, county, and Stone of New lorl-z, hove invented certain new and useful Improvements in Carlleuring Systems, of which the following u spccilicution.

- This application is in port it continuntion of my application No. 355,778, liled April 15, 1905, (Patent No. 814,285) and relates to a system or arrangement of the piping and other parts of a cor heating system, being especially important connection with the l urc regulator described in the aforesaid application, Without however solely for use in connection with such regulater.

The accompanying drmvings illustrate an embodiment of the inventions I Figure lis a perspective view of the principal ports of the system; Figs. 2 and 3 are sectional views of strainers used at different points ol the system; Fig; 4 is n sectional View of the pressure regulator. sectional view of a modified dctsil.

Referring now to the embodiment of the invention illustrated, the main trsinpipe (1 runs the entire length of the train and is supplied with steam from the locomotive at high pressure. Horizon-talbranches b conduct the steam from the trsin-pipe to piping onopposite sides of the cor constituting the heater. The entrance to the branch pipe I) i above the bottom or the train-pipe, and an unobstructed passage is left for dirt along the bottom of the train-pi c, and for stoaun around the outside of t e strainer 0, introducecl at the entrance of each of the branches b, and forming in tact parts of said branches; so that the steam flows around the outside of the strainers to clean them, and carries the dirtollong thev bottom of the trsin'pipe beyond them. Itvvill be understood that the-steam carries along through the trainpi e a quantity of scale, small pieces of rubber, and other dirt, and it is essential to the. roper Working of the valves that this dirt lie kept out. v

The ipes a and l) are below the floor of the car. l rom the end of the pipe I) on each side there is a vertical pi e cl at the upper end of which is an angle verve c of the usual or any suitable type the spii-rllc oi rich projects upwardly to a point access-ii;- c from within the The steam pisses from the valve being limitedthrough the gravity trap.

Fig. 5 isn' 12 through the regulator, which l designate {IS a whole by the letter f, to the h inter or system of radiating pipes arranged in any suitable nmnner in the car, and typiliei'l in the present case by apair ol" longitudinal radiating pics /i, from the latter ol" which the steam. and water of condensation run through downwardly inclined horizontal branches j and a vertical branch to a dounwnrdly inclined discharge pipe Z carrying near its end a thermostatic trap m at one side and a gravity trap 71 at the opposite side, and at its end beyond these traps n blow-out valve 0 the stem ol" which projects utuvzu'd to a point ncccssible from within the car. The pipes g and l'i may also be suitably inclined to insure the running off of the Water oi con- By these means the heater normally closed at its discharge end. water of condensation is purged at int: While the pressure is on through the thornstatic trap, and, jvhen the pressure is cut oil', When the steam is first turned on the blow-out valve 0 may be opened. to permit the rapid escape of air in the pipes; lhe arrangement of the parts in connection with the dischurgo pipc Z'is described inorefully and claimed in my application for Patent No. 2%,864, filed November 80, 1904. The vertical 'pipe (I with the valve e at its upper end Tetnl'dsthe passage into the regulator of any dirt which escapes through the strsinersqthe natural tendency being to drop to theibottoin of the vertical pipe d. In addition a strainer p is introduced between'ths hand valve 0 and the automatic regulator f. A steam pressure gage g is usually applied at the admission point of the radiating system.

The strainers c are preferably of the type illustrated in Fig. 3,each consisting oi it short length of pipe screw-threaded on the ends for connection to the main and brunch respcctively, and having a slitted or otherwise opertured head 1 projecting into the pipe a a short distance so as to be kept clean the current of passing steam, and also leaving free the, bottom of the train-pipe along which dirt is usually carried, and being shove such bottom so that the dirt will not ordinarily tend to run into the branch pipe.

[my dirt which is light enough to be carried through the screens 0 and u the vertical pi )e d (the latter forming it sort of dirt trsp) *1 lbs sto ped by the scr ivhich is'interposed in the upper horie-o l e. The preferred construction of the screen p is shown in Fig. 2. A cylinder tis extended .ferred to.

squarely across the pipe 8 with its lower end of the easing into the space beneath the flexible diaphragm, tending to lift it against the pressure of the spring 11, so that when the pressure in the system increases beyond that desired, the valve closes partially or entirely, or until the pressure again falls to the desired point; the double valve to x serving to regulate the pressure quickly and accurat-ely.

The pipes b and (Z may be connected by a tee y as in Fig. 5, the lower end of which is closed by a plug 2 which may be removed to clean out the accumulatedsediment.

What I claim is I 1. In a car heating system, in combination, a train pipe (1, a horizontal branch I) therefrom having a strainer c at the entrance to said branch and projecting into the train pipe, a vertical pipe projecting upward from said horizontal branch, an ad-- mission valve 6 at the upper end of said pipe d and accessible from within the car, a heater within the car, an automatic pressure regulator f between the admission valve and the heater, and a strainer 1) between the admission valve and the regulator, the entrance to said branch I) being above the bottom of the train pipe, and an unobstructed passage for dirt being left along the bottom of said train pipe and for steam around the outside of said strainer, whereby the steam flows around the outside of saidstrainer to clean it and carry the dirt beyond it.

2. Iii a car heating system, in combination, a train pipe a, a horizontal branch 6- therefrom having a strainerc at the entrance to said branch and projecting into the train pipe, a vertical branch d projecting upward from said horizontal branch, an admission valve e at the upper end of said pipe at and accessible from within the car, a heater within the car, an automatic pressure regulator f between the admisssion valve and the,

heater, and a strainer 19 between the admis sion valve and the regulator, the entrance to said branch 19 being above the bottom of the train pipe, and an unobstructed passage for dirt being left along the bottom of said train pipe. and for steam around the outside of said strainer, whereby the steam flows around the outside of said strainer to clean it and carry the dirt beyond it, said strainer 0 comprising a short length of pipe connected at one end to the main and forming a part of the branch and having a slitted head 1' constituting the portion which projects into the main. pipe, and said strainer p comprising a fitting extending squarely across the pipe and having a removable cap a and an in closed removable perforated cylinder 13, the lower end of the fitting and cylinder thus forming a dirt trap which may be opened and cleaned.

3 in a car heating system, in combination, a train pipe a, a horizontal branch I) therefrom aving a strainer c at the entrance to said branch, a vertical pipe d projecting upward from said horizontal branch, an admission valve 6 at-the upper end of said pipe (1 and accessible from within the car, a heater within the car, an automatio pressure regulator f between the admission valve and the heater, and a strainer p between the admission valve and the regulator.

In witness whereof, have'hereunto signed my name in the presence of two subscribing witnesses.
